Loose a gun at a match...no worries...I can hang around and help paste... loose a gun on the street....not for me. I will stick with quality specific glove fitting leather holsters. Lost Guns (sidearms coming out of holsters when they shouldn’t) Are like ND’s. Few own up to it or the story goes wide.
A properly made kydex holster has loads of retention and isn’t going to come out. They’re “glove fitting specific.” If you’re using some Bubba special made in some guys garage that wasn’t formed properly then sure. Unless you’re talking about a gun grab but you’re just as susceptible to that as you would be with a leather holster.
